Aristide Baratin (University of Waterloo), Dr Florian Girelli (University of Waterloo)16/06/2014, 13:45Theoretical Physics / Physique théorique (DTP-DPT)Invited Speaker / Conférencier invitéThe definition of a quantum theory for gravity is a long standing problem. Currently, different approaches exist. In this talk, I will present the main ideas behind Loop Quantum Gravity and the Spinfoam frameworks. These are attempts to quantize directly General Relativity using respectively Dirac’s canonical quantization and Feynman’s path integral quantization. I will give an overview of...Go to contribution page

Prof. Ue-Li Pen (University of Toronto, CITA)16/06/2014, 14:15Theoretical Physics / Physique théorique (DTP-DPT)Invited Speaker / Conférencier invitéRecent implications of results from quantum information theory applied to black holes has led to the confusing conclusions that requires either abandoning the equivalence principle (e.g. the firewall picture), or the no-hair theorem (e.g. the fuzzball picture), or even more unpalatable options. The recent discovery of a pulsar orbiting a black hole opens up new possibilities for tests...Go to contribution page

Robert Mann (U)16/06/2014, 14:45Theoretical Physics / Physique théorique (DTP-DPT)Oral (Non-Student) / orale (non-étudiant)The cornerstone of thermodynamics is the first law, which for a black hole identifies thermodynamic energy with its mass, temperature with its surface gravity, and entropy with its area. Recent work that posits the identification of a cosmological constant with thermodynamic pressure results in black holes behaving somewhat like chemical systems, with pressure-volume terms appearing in...Go to contribution page

Arundhati Dasgupta (University of Lethbridge)16/06/2014, 15:00Theoretical Physics / Physique théorique (DTP-DPT)Oral (Non-Student) / orale (non-étudiant)We formulate quantum field theory in accelerated frames using Prigogine transformations. We then derive a background independent formulation of such transforms, and attempt a new formulation of quantum gravity.Go to contribution page
